Your old hillbilly friend must not shoot a lot then. Those of us that put thousands of rounds downrange each year can tell you that method is about useless. My methods are dependent on which rifle,handgun, or muzzleloader I am working on at the time. It can also be dependent upon which load/bullet I am using as well. Leading, copper fouling, even some of the more caustic powders can also come into play in deciding which cleaning method one uses. Or SHOULD be using.
